Chapter 4: Parameter passing 61
In the iSmart, almost all the function block can use other function block’s current value as its
preset value. This process we called data transmission. This chapter will describe some regulation
about data transmission.
iSmart inner data type
All the data stored in SMT inner system are integer. Even through some parameter likes
“A01 = 9.99V” display in LED, in fact “9.99” stored in SMT inner system is “999”. Only in
display stage, the decimal point of “9.99” added according to its physical significance. When
analog variable and other function block current value passed to other function block or
analog output as preset value, essentially just integers passed. When need to display those
passed integer preset value in LED, decimal point will be added according to physical
significance.
Exa
mple1:
A05 current value passing to other function block as preset value:
When A05=2.34V, A05’s inner value 234 is passed to other function block as preset value.
Passing to AQ01 automatically as 2.34V, Passing to B001 (G01) automatically as 2.34V, Passing
to B002(T01 time base is 0.01s) automatically as 2.34s, Passing to B003(T02 time base is 0.1s)
automatically as 23.4s, Passing to B004(T03 time base is 1s) automatically as 234s, Passing to
B005(C01) automatically as 234:
